SPECIFICATION forming part of Letters Patent No. 451,272, dated April 28,1891.

Application filed May 15, 1890. Serial No. 351,940. (No model.)

To (all whom it may concern;

Be it known that I, CHARLES L. HALSTEAD, a citizen of the United States, residing at La Crosse, in the county of La Crosse and State of 'lVisconsin, have invented certain new and useful Improvements in the Art of Securing Hose-Bands to Metallic Nozzles, Joints, or Couplings,-&c.; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in a device for securing hose-bands; and the object of my invention is to provide a devicewhereby said bands can be quickly and rigidly secured around the hose, so that the hose will be so closely compressed againstthe coupling that leakage will be prevented. I attain said object by a certain construction and arrangement of parts fully described in this specification and illustrated in the accompanying drawings, in which there are the slots a a, which are adapted to receive and hold the ends 7) b of the hoseband B.

The plate 0 is swiveled upon the lower end This plate is made of the thumb-screw D.

around the hose.

with the portion 0 cut-away, and is concaved upon the under side so as to fit c sely against thehose and hold the band in Mal position when the device is being ope ted. Said portion 0 is cut away to provide 11 opening through which the ends of the band B may pass, and by means of which the same are held in position while the ends I) Z) are be ing adjusted in the slots a a of the plate A and secured around the hose.

In applying the band B the same is first bent in a circular form; the ends passing through the loop in the end formed by the cross-bar Z). (See Fig. l.) The band is then adjusted to the hose and the device applied as shown in Fig. 2. The thumbscrew Dis then operated, which draws the band B tightly The ends of the band are then bent over by the forward movement of the device, after which the device is removed and the ends of the band bent flatly down,as indicated by the dotted lines in Fig. 4.

hat I claim is- Y In a device for securing hose-bands, the thumb-screw D, in combination with the plate 0, swiveled upon the lower end of said th u mbscrew, said plate having the portion 0' cut away, and the plate A, having in each end the slots a a and provided with a centrallythreaded socket adapted to the thumb-screw D and in which the same works, substantially as described, and for the purpose set forth.

In testimony whereof I at'fix my signature in presence of two witnesses.

CHARLES L. HALS'IEAD.
